Title
(EN) AXIAL FLOW FLUID DEVICE
(FR) MÉCANISME POUR ÉCOULEMENT AXIAL DE FLUIDE
(JA) 軸流流体装置
Abstract
(EN)
An axial flow fluid device in which blade rows (3, 4) having blades (31, 41) arranged around an axis are installed in a flow passage (23) for a fluid (Y). The axial flow fluid device has a turbulent flow eliminating means (8) for eliminating turbulent flow components (Y1 to Y4) in the fluid (Y) fed to the blade rows (3, 4). The axial flow fluid device reduces components of broadband noise out of the components of noise generated by the interference of the fluid with the blades.
(FR)
L'invention concerne un mécanisme pour écoulement axial de fluide dans lequel des grilles d'aubes directrices (3, 4) possédant des aubes (31, 41) placées autour d'un axe sont installées dans un passage de circulation (23) d'un fluide (Y). Le mécanisme pour écoulement axial de fluide comporte un moyen (8) d'élimination de turbulences permettant d'éliminer les composantes d'écoulement turbulent (Y1 à Y4) dans le fluide (Y) alimentant les grilles d'aubes directrices (3, 4). Le mécanisme pour écoulement axial de fluide réduit les composantes de bruit à large bande des composantes de bruit généré par l'interférence du fluide avec les aubes.
(JA)
 複数の翼31,41が軸回りに配列された翼列3,4が流体Yの流路23内に設置される軸流流体装置であって、上記翼列3,4に供給される流体Y中の乱流成分Y1~Y4を除去する乱流除去手段8を備える軸流流体装置。本軸流流体装置により、流体と翼とが干渉することによって発生する騒音のうち広帯域騒音を低減する。
